There is a Facebook page- vermont bird fanciers- that I've rehomed a few Roos on. I've also donated to VINS.
Be careful in that group. I'm in there too and there is rampant respiratory illness in there. I had to cull my entire flock and start over earlier this year after getting birds from a lady and them giving my whole flock coryza.
And it's happened to at least three other people too in the last couple months, and that's just what I know of, to say nothing of all the people who think chickens just get colds and throw medications at them until symptoms go away and don't post about it.
And I know who those three people bought from, and one of the sellers is still always on there, pushing birds and trying to sell more.
So just be careful if you're ever trying to buy bird on there.
